You don't need the check valve.

 

Why not? What makes you think this? I paid for a catch can with a check valve, all I got was the catch can.

 

 

It does have a check valve. It's attached to the fitting coming off the cc.

 

 

And I don't think so. I can blow air through the tubing and the can without any restriction. And from my research, it looks like the videos put out by RX show them having a check valve in line with the hosing on the can.

 

Also, if you look at this picture, posted by Crf450r420 on page 25 of this thread, in post # 367, you can clearly see the check valve in-line with the screw type fitting on the right side of the can. Mine did not come with this part.

My dealership said my catch can wasn't needed and wouldn't catch anything. I opened it in there shop after 2,000 miles and let it run on the floor. Lol

So, I added a second output fitting to my Original RX catch can. I had been emailing with the RevExtreme folks about the benefits of a dual output can, and they were gracious enough to send me the par

Are you saying yours does not look like the pic? My Rx cc looks just like the pic and has the valve.

 

Correct. I am missing the valve. Seen here.

Has to be an oversight. They should be able to ship that out.

 

I figured as much. But didn't know why people said the check valve wasn't necessary. It helps keep even more oil vapor out of the intake.

Yeah OK... Do the Other cans come with a check valve?? NO THEY do not... It's really for boosted motors and HIGH HP BUILDS that have a lot on crank case pressure and blow-by and I'm 100% positive your motor is not one of those builds. So no you don't need a $2.00 valve. This was confirmed by Tracy.

Youre missing the point. I bought something that said it was supposed to come with a valve. I didn't get the valve. I want my moneys worth. Yea it might cost $2.00. But its the principle.

 

And every video with Tracy I see installing a catch can has the valve on it....

Well I can only hope my order from RX comes with the check valve although on a side note the good news is I order it last Wednesday and it arrived Friday so it was pretty quick to me and I order it in summit white so will post once installed on Monday since PO is closed today.

Your right my friends 15' Stingray does not have one either. I might just experiment with my truck and take my check valve just to see why it's needed.

Just ordered my rx can. I see most of you mount the can on the brake booster. I was thinking about putting in near the extra battery spot. I see the concern with temperatures but will it really be that much of an issue? I've read through almost the entire thread. When it's negative out here I see running into the same issues whether it's mounted near the back or in front.

The cooler the can the better it will work as more of the evaporated water/oil will condense on the side of the can. I wanted to mount mine to the low side ac line to keep it cool, but it was to much work to get done in the time I had to do it.

The check valve doesn't keep oil out of the intake it keeps back pressure from a turbo charger from going through the can in reverse and pressurizing your crankcase thus blowing out the oil seals in the crankcase. You don't technically need the check valve because you don't have a turbo but I agree, you paid for it and it should be in there as an extra layer of protection. I would call them up they should send it out to you free of charge. Just a minor over site.

      OCI, not when but why?

      By Atlas · Posted

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.

      Will not stay in Reverse

      By TheGeek · Posted

      I have a LTZ and it has the shifter in the console, which I like, but, every now and then, it will not stay in Reverse. I go through all the motions, hold the button in, push the shifter forward and watch the dash.  The big red R comes on and also the back up camera.  Then, it just pops out of Reverse with the shifter all the way forward.  So then the game begins.  Back and to Drive, Reverse.  This goes on 8 - 10 times. Very frustrating. Had it back to the dealer and they replaced some kind of computer, but it is now happing again. It is so bad, my wife will not drive the truck, she is afraid of being stuck somewhere.    Anyone else with this PIA problem?

      I see where you’re going and I can appreciate that. Statistics can be misleading because of the word average. They say statistics show the average cost of a new vehicle is about 50k. The average monthly payment is close to 1000 dollars a month. That’s statistics for you. I know very few people who pay that.
